This is a gold-plated 3C trumpet mouthpiece (no Q mark) from Taguchi Wind Instrument Workshop, which was established independently from Willie's. It will be sent in its original box. It was used for about 5 minutes a day for 3 days. It was a good item that produced a good sound from low to high notes, but I have decided to continue using the custom-made mouthpieces I have, so I am selling this one. There is a ring on the part that touches the end of the mouthpiece receiver (see photo 4). Please be aware of this. Trumpet Mouthpiece Gold Plated GP MASAKI Taguchi Wind Instrument Workshop 3C
